🕐
Frequency differs. The frequency in Sao Tome and Principe (50Hz) differs from the United States (60Hz). Be extra careful with motorised devices and items with timers or motors (clocks, shavers, some medical devices).
Many chargers (phones, laptops, cameras) are labelled INPUT: 100–240V, 50/60Hz — those work anywhere and only need a plug adapter, never a converter. Always check the label.
